perchloric acid
its called the "STRONG ACID"
A strong acid is an acid which completely dissociates (this means that it breaks up into a hydrogen cation and some anion) in water. All other acids are considered weak.
because not all acids are strong some can be an acid and an alkaline and some just a weaker acid
strong acids dissociate completely into ions in water. i.e. HCl dissociates into H+ and Cl- ions. Weak acids only dissociate partially, therefore they are in an equilibrium state where there is some acid remaining and some ions in solution.
That will depend not only on the metal but also on the acid. Some strong acids will dissolve almost all metals almost instantly, some weak acids will do nothing at all to any metal. Some metals (e.g. zinc) are corroded or even dissolved by most acids, some metals (e.g. gold) are totally unaffected except by certain mixtures of very strong acids.
Nitric acid reacts strongly with many metals.
Buffers are weak acids or bases that can react with strong acids or bases to prevent sharp, sudden changes in pH....
Some metals have very strong metallic bonds which acid cannot break.
Citric, Boric, Hydrochloric.
It is a matter of memorization. There are only 6 common strong acids, some sources list 7 or 8. All other acids can be considered weak. The six commonly listed strong acids are: Hydrochloric acid: HCl Hydrobromic acid: HBr Hydroiodic acid: HI Perchloric acid: HClO4 Nitric acid: HNO3 Sulfuric acid: H2SO4 Two acids sometimes cited as strong acids are: Periodic acid: HIO4 Chloric acid: HClO3
All acids have H in them. Some examples of acids are: Carbonic acid Hydrochloric acid Sulphuric acid
Acid, of course. Many live in naturally occurring organic acids, but some can line in acids that are strong, such as sulfuric and nitric acid.
